Incoloy 926 (UNS N08926, equivalent to 1.4529 / 25-6Mo) is a high-molybdenum nitrogen-bearing superaustenitic alloy with PREN around 43–47. Pitting and crevice resistance approach Inconel 625 at markedly lower cost.
As a manufacturer and global exporter of special alloys since 2012, Shanghai Hangbo Alloy Group Co., Ltd. supplies Incoloy 926 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), seamless tubes & pipes (φ6–630 mm OD, 0.5–40 mm wall), forgings & rolled rings (up to 7500 kg, 3500 mm OD), flanges & pipe fittings (Class 150–2500, DN15–DN1200) — all with EN 10204 3.1 certified material test reports.

Frequently asked questions
How does Incoloy 926 relate to 254SMO?
They are very close in chemistry and performance — 926 (N08926) and 254SMO (S31254) are both 6% Mo superaustenitic grades with PREN in the 43–47 range and are often interchangeable. Final selection should follow the applicable standard, the product form required and design allowable stresses; Hangbo supplies both.
What forms and sizes are available?
We supply Incoloy 926 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), seamless tubes & pipes (φ6–630 mm OD, 0.5–40 mm wall), forgings & rolled rings (up to 7500 kg, 3500 mm OD), flanges & pipe fittings (Class 150–2500, DN15–DN1200). Custom lengths, tolerances and machining to drawing are available on request.
What is the MOQ and lead time?
MOQ is flexible — trial orders from a single piece are welcome. Stock sizes ship in 3–7 days; custom forgings and machined parts typically 15–35 days depending on quantity and process.
Can you provide third-party inspection and shipping to my port?
Yes. SGS / BV / TUV or your nominated inspector can witness all tests before shipment. Full export documentation is provided, and we ship worldwide by sea or air on FOB, CIF or DDP terms.
